Specification of Letters Patent;

Application filed October 18, 1915. Serial No. 126,386;

To all whom t may concern:

Be it known that I, ANNA M. EcKnNnoD, a citizen of the United States, residing at Altoona, in the county of Blair and State of l be conveniently and effectively applied to or removed from a dust bag. The invention consists in the details of construction and in the combination and arrangement ofthe several parts of my improved dust bag whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel'features of the invention will hereinafter be definitely claimed.v

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Y Figure 1 is a fragmentary view in section illustrating a dust bag constructed in accordance with an embodiment of my invention and in applied position; and

Fig. 2 is a view in plan of my improved dust bag, detached, and in a flattened state.

As disclosed in the accompanying drawings, D `denotes the dust box ofV a vacuum cleaner provided at one end with the entrance or insertion opening lV through which the dust bag B is adapted to be applied or removed. I wish it to be understood that it is not my purpose to limit myself to any particular form of vacuum cleaner as the vacuum cleaner per se forms no part of my present invention.

My improved dust bag is formed of suitable material and has its open end flared outwardly, as indicated at 2,'so that when the bag is inserted within the dust box D, the open-end marginal portions thereof may be readily and conveniently folded to afford a tight engagement between said open end of the bag and the outer wall of lthe dust box as is particularlyshown in Fig. l. By having the open end of the bag flared as disclosed in Fig. 2, it will be'perceived that when the nozzle N is in applied position,

Patented Feb. 2.50, 1917.

the bag B will be effectively clamped in f applied position and that when said nozzle N is removed the bag may be readily and conveniently withdrawn and if desired said bag together with its contents Vmay be burned, as it is to be understood that the bag is not intended for use afterit has once Y been substantially filled. Y

It is also preferred that the longitudinal marginal portions of the bag be creased or folded as indicated by dotted lines at 3 in Fig. 2 so that the width of thebag maybe conveniently reduced in order to facilitate its insertion within the dust box through the entrance opening l thereof and so that the Y portion of the bag within the dust box D may be readily expanded.

The bag'B is preferably formed of paper and atA apredetermined point inwardly of its open end is provided with a transverse series of restricted openings or perforations 4 through which the air is drawn. While the air isdrawn through the perforations 4t it has been fully demonstrated in practice that the'dirt drawn through the opening 1 vwill be collected `within the bag B.

From the foregoing description, it is thought to be obvious thatV a dust bag constructed in accordance withlmy invention is of anl extremely simple and comparatively inexpensive nature yand is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modiiication without material departure from the principlesl and spirit thereof and for thisV reason I do not wish to be understood as limiting myself to the vprecise arrangement and formation yof the several parts herein shown'in carrying o-utmy invention in practice, except as vhereinafter claimed.

I claim: lwardly of its open end, the remaining porl. A dust bag for vacuum cleaners protions of the bag being imperforate. l0 vided with perforations at a predetermined In testimony whereof hereunto affix my point inwardly of its open end, the remainsignature in the presence of two witnesses.

5 ing points of the bag being imperforate. ANNA M. ECKENROD. i
